KNITTING-MACHINE FOR KNITTING DOUBLE-THREADED STRIPED FABRICS.

SPECIFICATION forming part of Letters Patent No. 263,125, dated August22, 1882. Application filed January 27, 1882. (No model.)

To all whom it may concern:

Be it known that I, JAMES DENTON, ofAm- 'sterdam, in the county ofMontgomery, in the State of New York, have invented new and usefulImprovements in Knittiug-Machinesibr Knitting Double-Threaded StripedFabrics, of which the following, taken in connection with theaccompayiug drawings, is a full, clear, and exact description.

This invention relates to anovel, simple, and effective device forproducing striped knitted fabrics, as hereinafter fully explained.

Referring to the annexed drawings, Figure l is a plan view of thatportion of a knittingmachine to which my invention is applied. Fig. 2 isan elevation illustrating the mechanism employed for throwing thestriping wheel in and out of connection with theneedle-cylinder, andFig. 3 is a plan view of the patterndisk.

Similar letters of reference indicate corresponding parts.

A represents the needle-cylinder of a circular-knitting machine, and a athe bearded needles, carried vertically on the periphery of the cylinderA.

B is the so-called burr or loop-wheel, which applies the knittin gyarnor thread to the needles, and h h are two fixed or stationary threadedguides of the ordinary form, arranged with theirforward endsin proximityto the loopzontal pivoted disk, arranged at the outside of theneedle'cylinder, and pressing against the beards of the needles, so asto close them and allow the previously-depressed loops to slip up overthe beards of the needles.

E is the landing-wheel, arranged on the inside of the needle-cylinder,and operating to threads inside of the beards of the needles.

The ordinary operation of the aforesaid mechanisms on the two threadslying one above the other in the beards of the needles crowds the lowerof said threads more or less back of the upper thread, and therebyproduces a mottled or variegated fabric. This I convert into a strippedconfiguration by means of asmall wheel, which I will term thestripingwheel, designated by the letter Gr in the drawings. Said wheelIplace between the landingwheel E and knocking-over wheel F and on theoutside of the needle-cylinder A, as illustrated in Fig. 1 of thedrawings, said striping-wheel being provided on its periphery withoblique wings or thin plates, similar to those of the loop-wheel, butpreferably with shorter nibs or hooks on the ends of said wings, orentirely without such nibs. It is pivoted on a suitable support inproximity to the needlecylinder, and has its Wings playing in theinterstices between the needles. During the rotation of theneedle-cylinder the needles press successively against the wings of thestripingwheel, and thereby impart a rotary motion to said wheel, theaxis of which is in such position .in relation to the periphery of theneedle-cylinder as to cause the striping-wheel to rotate in a directionwhich draws its wings from the base of the needles upward and outwardfrom the needle-cylinder similar to .the movement of the wings of thewell-known loop-wheel. In thus playing between the needles the wings ofgo the striping-wheel engage the lower and rearwardly-disposed threadand draw the same outward or toward the front or face of the fabric, andthereby produce nearly plain colors at opposite sides of the fabric.Hence by throwing the striping-wheel G alternately and at regularintervals in and out ofengagement with the needles alternate mottled andplain stripes are produced in the fabric. To accomplish thisautomatically with the operation of too the machine, I mount thestriping-wheel G on the arbor 1), arranged movably toward'and from theneedle-cylinder, and connect. to said arbor an elbow-lever, c, pivotedon a fixed standard, and having its free end riding on a horizontalrotary cam-disk or pattern-disk, H, which has on its upper surface anelevated segmental track, 0, arranged in such relative position as tomove under the free end of the lever 0 during the rotation of said diskH. This movement raises the free end of the lever c, and thereby swingsthe opposite end thereof away from the needle-cylinder and carries withit the striping-wheel G into adorniant position. So soon as the free endof the lever cleaves the track 6 the striping-wheel falls back towardthe needle-cylinder and resumes its operation on the threads in processof bein g knitted, as before described.

The period of intermission between thedormant and operative positions ofthe stripingwheel are regulated by the length of the raised track or camc.

The pattern-disk or cam-disk H can be operated automatically withthemovement of the needle-cylinder by any suitable known mechanismcapable of transmitting the requisite motion. For a mere exemplificationof the transmitting medium I have shown in the annexed drawings apinion, m, on the shaft of the cam-disk c, which pinion, by means ofintermediate gears, a it, receives motion from a gear fixed to thespindle of the needle-cylinder.

Havingdescribed my invention, what 1 claim as new, and desire to secureby Letters Patent, is-

1. The combination, with the needle-cylinder A, needles a, loop-wheel B,landing-wheel E, and knocking-over wheel F, of two fixed or stationarythread-guides, h h, arranged at different heights, and thestriping-wheel G, arranged between the landing-wheel and knocking-overwheel, and having wings playing between the needles, substantially asdescribed and shown, for the purpose set forth.

2. In combination with the needle-cylinder A andbearded needles a, thestriping-whee] G, mounted on a movable support, and mechanism connectingsaid striping-wheel with the needle cylinder, whereby the striping wheelis automatically thrown in and outofengagement with the needles,substantially as set forth and shown.

In testimony whereofI have hereunto signed my name and affixed my seal,in the presence of two attesting witnesses, at Syracuse,in the countyofOnondaga, in the State ofNew York, this 6th day of January, 1882.
